android.security.KeyChainException：java.lang.IllegalStateException：UID [英] android.security.KeyChainException: java.lang.IllegalStateException: uid

问题描述

错误：

  android.security.KeyChainException：java.lang.IllegalStateException：UID 10111没有权限访问请求的别名
 

code：

 新主题（新的Runnable（）{        公共无效的run（）{
            尝试{
                X509证书[] = myCertificates KeyChain.getCertificateChain（MainActivity.thisServerCertificate）;
                如果（myCertificates！= NULL）
                {
                    的System.out.println（myCertificates大小+ myCertificates.length）;                    的for（int i = 0; I＆LT; myCertificates.length;我++）
                    {
                        的System.out.println（myCertificates我=+ I ++ myCertificates [I]）;
                    }
                }
            }赶上（KeyChainException E）{
                // TODO自动生成catch块
                e.printStackTrace（）;
            }赶上（InterruptedException的E）{
                // TODO自动生成catch块
                e.printStackTrace（）;
            }
            赶上（例外五）{
                // TODO自动生成catch块
                e.printStackTrace（）;
            }
        }
    }）。开始（）;
 

解决方案

的钥匙链类需要应用程序调用 choosePrivateKeyAlias​​（）至少一次应用程序之前调用安装在 getPrivateKey（）或 getCertificateChain（）。因此，即使一个事先知道的别名，在 choosePrivateKeyAlias​​（）必须至少调用一次，否则就没有应用程序和内部数据库<$ C之间建立信任$ C>钥匙链使用。

Error:

android.security.KeyChainException: java.lang.IllegalStateException: uid 10111 doesn't have permission to access the requested alias

Code:

new Thread(new Runnable() {

        public void run() {
            try {
                X509Certificate[] myCertificates=KeyChain.getCertificateChain(MainActivity.this, "ServerCertificate");
                if(myCertificates!=null)
                {
                    System.out.println("myCertificates size "+myCertificates.length);

                    for(int i=0;i<myCertificates.length;i++)
                    {
                        System.out.println("myCertificates i= "+i+"    "+myCertificates[i]);
                    }
                }
            } catch (KeyChainException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            catch (Exception e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
    }).start();

解决方案

The KeyChain class requires the application to call choosePrivateKeyAlias() at least once after the application is installed before calling getPrivateKey() or getCertificateChain(). So even if one knows the alias beforehand, the choosePrivateKeyAlias() must be called at least once, otherwise there is no trust established between the app and the internal database that KeyChain uses.
